3 Bears rookies worth watching

There are a lot of stud Bears players throughout the history of the franchise from the early 1900s to current day, so compiling a list of the 20 greatest Bears ever was quite hard. Here are the 20 we think are the greatest ever. Tell us yours at our Facebook page. See our vintage Bears photos here.Want more? Discuss this article and others on RedEye's Facebook page.

With training camp only three weeks away, new coach Marc Trestman will have a lot of tough decisions as he tries to lead the Bears to the playoffs. Brian Urlacher's departure, rebuilding the offensive line, reviving an aging defense and protecting Jay Cutler will require the Bears to make considerable use of young talent.

Of the 18 rookies currently on the roster, only a few will make the final, 53-man roster. Here are three who could make the biggest impact this season:

Jon Bostic, linebacker

With Brian Urlacher's retirement, the Bears need someone to man the middle linebacker position he held for more than a decade. Bostic could be that guy. His football intelligence, instincts, strength, speed and power could be a perfect fit for the Bears' new defense. Regardless of whether Bostic starts this year, expect him rack up the tackles. And study lots of Briggs/Urlacher/Butkus/Singletary film.

Although his offseason workouts have been limited due to academic commitments at Oregon, the son of Hall of Fame defensive end Howie Long has showcased impressive skills. He can play both guard and tackle thanks to his height, quickness and wing span. This is important to a team looking to provide better protection for its star quarterback. Which means K-Cav and baby Cameron are Long's biggest fans.

Michael Ford, running back

Ford was signed as an undrafted free agent after the NFL Draft in April. But he has made quite an impression since being added to the roster in May. He is one of the faster running backs on the team and has electrifying agility. Ford also can contribute on special teams, perhaps filling in as a return man. With Devin Hester and Eric Weems in that role as well, opponents may never kick off or punt to the Bears again.
